Title:
SHAPE MEMORY BISTABLE ACTUATOR
Document Type and Number:
Japanese Patent JP2005320960
Kind Code:
A
Abstract:

To provide a shape memory actuator of bistable type.

This shape memory bistable actuator is movably installed on a fixed support structure 2, and comprises an element 3 having a middle position called a dead point and two end positions. A spring means 7 forces to return the movable element 3 to either of the end positions according to what portion the dead point is present. A shape memory means 5 is installed to move the movable element 3 from either of the end positions against the action of the spring means 7 until it passes over at least the dead point. Since the movable element is advanced to a new specified working position and, even if the shape memory means is non-active, the spring means is installed at that position to hold the shape memory means, when the movable element is passed over the dead point, the operation of the shape memory means 5 is stopped.
